BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed February 5, 1914. Serial No. 816,708.

To all whom it may concern Be it known that I, OTTo KAMPFE, a citizen ofthe United States of America, residing at New York city, borough ofBrooklyn, county of Kings, and State of New York, have invented certainnew and useful 1m provements in Bottle-Closures, of which the followingis a full, clear, and exactdescription.

This invention relates to improvements in closures more particularlyadapted for milkbottles such as are commonly used by dairymen to delivermilk for family purposes.

The object of this invention is to provide an inexpensive sanitaryclosure or stopper that can be easily and quickly applied to a milkbottle, the closure acting to keep the contents of the bottle free fromdirt, flies or contact with the air.

lVhile my improved closure will accomplish the above results, it willnot, in the least, interfere with the pouring of the milk from thebottle, as the closure will fall away from the mouth of the bottle whenthe bottle is tipped for the purpose of pouring milk therefrom.

The device can be easily inserted into the mouth of the bottle by simplycompressing the clamping or locking element or anchor for the cap, andit can be easily removed by a strong pull. Other features of improvementwill hereinafter appear.

I will now proceed to describe my invention in detail, the novelfeatures of which I will point out in the appended claims, referencebeing had to the accompanying drawing, forming part hereof, whereinFigure 1 is a sectional view of the upper end of a milk bottle having myimproved closure applied thereto; Fig. 2 is a sectional top plan viewthereof on a reduced scale, the section being taken on a line 2-2 inFig. 1; Fig. 3 is a diagrammatic View illustrating the device inposition for pouring fluid therefrom; and Fig. 4} is a view similar toFig. 1 illustrating a modified form of closure.

As herein shown my improved bottle closure 'is illustrated as applied toa milk bottle and consists of a plate or cap 1 formed to lie fiat or inclose contact with the upper edge of the bottle and over the mouth 2thereof. As is usual in this class of bottle, the said bottle 3 isprovided with a counter-bore 8 within which the paper or celluloid plugsor disks now usually employed, are forced.

My improved closure is designed to take the place of these paper plugsor disks.

To maintain the plate or cap 1 in proper relationship, at all times,with the open end of the bottle I employ a clamp or anchor 1 providedwith a spindle 5 which passes through an opening 5 in the plate 1, thespindle 5 being provided with a ring or stop 6 at the outer end thereof.In this instance, the clamp or anchor 4 consists of a resilient coil ofwire, preferably German silver or other non-corroding material. Forsanitary reasons the plate 1 is preferably made of Germansilver,aluminum or some material that will not rust or corrode, the design ofthe plate being optional.

The coiled anchor or clamp 4: will normally be larger in diameter thanthe counterbore 3 hence to insert it into the counterbore 3 it will benecessary to slightly compress it. After the anchor has been insertedinto the counter-bore, it will be released and allowed to expand,thereby pressing firmly against the side wall of the counterbore andthus anchoring it therein. To remove the anchor, a strong pull will benecessary; consequently, it will not fall out by gravity when the bottleis tipped.

As long as the bottle remains in a vertical position, or even at anangle, provided the angle is not sufficient to cause the cap to breakcontact with the bottle, the mouth of the bottle will be covered; hencethe contents will be kept free from contact with the air or dirt.

To cause the contents of the bottle to flow therefrom, it is butnecessary to tip the bottle, as shown in Fig. 3, at which time the plate1 will fall away therefrom, providing a passage through which thecontents of the bottle will flow. The stop 6 will prevent the cap fromfalling off the spindle or guide 5. When the bottle is again tipped backto its normal position, the cap or plate 1 will fall into place, asshown in Fig. 1.

In the form of device illustrated in Fig. 4, I provide a lock 7 for theplate 1, the same consisting of a ball or block of rubber, leather orthe like or any substance having a natural tendency to hug or rip thespindle 5, the block or ball being slidably mounted on the spindle asshown. When the lock 7 is pressed down upon the plate, as shown in Fig.4, the bottle can be tipped or can fall over, without spilling thecontents thereof, as the said lock will firmly hold the cap against thebottle; but when the cap is to be released, the block 7 can readily bemoved to the dotted line position (Fig. 4).

Having nou described my invention, What 1 claim and desire to secure byLetters Patent is:

1. A bottle closure consisting of a resilient clamp adapted forinsertion into the mouth of a bottle, a centrally located stationaryguide projecting vertically therefrom, a cover plate movable on saidguide and pro vided With a central opening adapted for the free passagetherethrough of said guide, and a stop at the outer end oi said guide.

2. A bottle closure consisting of a coiled clamp of resilient material,a rigid guide extending therefrom, and a cover-plate slidably mounted onsaid guide, and adapted to move by gravity longitudinally thereof.

Copies of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents.

3. A bottle closure consisting of a'coiled clamp of resilient material,a rigid guide extending therefrom, a cover plate slidably mountedthereupon, and a lock for said plate carried by said guide.

4. A bottle-closure comprising a clamp adapted for insertion into themouth ofa bottle, a stationary post projecting from said clamp, and acover-plate slidably mounted on said post and adapted to tilt, when freefrom contact With the bottle, in a direction corresponding with anytilting of the bottle.

Signed at New York city, N. Y., this 4 day of February, 1914.

I OTTO KAMPFE.
